WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 418,538, dated December 31 1889.

Application filed October 21, 1889- T at whom it may concern.

Be it known that I, AROHIBALD SPENOE, a subject of the Queen of Great Britain, residing at the cityof Montreal, in the District of Montreal and Province of Quebec, 0anada, have invented new and useful Improvements in Water-Heaters; and I do hereby declarethat the following is a full, clear, and exact description of the same.

My present invention has reference to further improvements in the water-heater for which Letters Patent'of the United States were granted to me on the 8th day of March, A. D. 1887, under No. 359,105; and it consists in furtherimprovements in the construction and arrangement of the connection which unites the water-spaces in the furnace with the sections; and the object of my invention is 'to form both the said connections and sections with less labor of molding and consequent cost or expense. I attain this object by the water-heater illustrated in the accompanying drawings, in which similar letters 0 7 reference indicate like parts.

Figure 1 is an elevation of the water-heater. Fig. 2 is a vertical section of the water-heater, taken about the position of the line :0 in Fig. 4. Fig. 3 is a vertical section of the waterconnection as formed in part on each section. The section is taken at line 00 Fig. 1, which is the same position as line a, Fig. 4:. Fig. 4 is a plan of the top or first section; Fig. 5 is a vertical section of the top or first section taken on linear, Fig. 4. Fig. 6 is a plan of the second section. Fig. 7 is a vertical section ofthe second section taken on line as, Fig. 6. Fig. Sis a plan of the third section. Fig. 9 is a vertical section of the third section taken on line 00 Fig. 8.

I would first generally remark that in the heater about to be described the sections, per 32, are the same as heretofore shown in my said previous patent, only that in this case the corresponding portions of the water-connection are made integral with the various sections.

The invention is illustrated by a heater composed of five sections, there being three diiferent species of sections of the same ge- Serial No. 327,746. (No model.)

nus combined in one water-heater. After the first or top section the second and third sections alternate, and thus a heater may be arranged with any greater or less number of sections than five, as shown.

Letter A is the furnace, which is substantially similar to that shown in my aforesaid patent. I I

B is the top or first section. This is preferably made with a central opening 17, as heretofore.

b is a projecting portion forming the waterwconnection integral with the section B, and is divided into two parts by a vertical diaphragm 19 One of the divisions thus formed is closed at the top bya horizontal diaphragm 12 The second sectionGis preferably provided with the openings 0, as before. It is also provided with a projection a, divided by a vertical diaphragm 0 into two parts, and this diaphragm is arranged to agree and form a joint with the diaphragm 17 The third section D is exactly the same as the section B, only that the diaphragm b is omitted. It has a central opening d, a proagrees and forms a joint with the diaphragm 0 If the heater is to have a greater number of sections than three, the sections 0 and D are repeated alternately for the number of sections required.

It will be'seen by Fig. 3 that when the sections are built together, being provided with flanges e, secured together with bolts and nuts f, that the diaphragms b 0 and d form practically one continuous diaphragm, and that the water rising from the water-casing g of the furnace A is arranged to connect with the side 1, or that which at the top has the diaphragm 19 so that the said water is caused to pass or circulate through all the sections in the same direction, as shown by the arrows in Figs. 4 and 6.

vided with suitable necks i, for connecting the circulating-pipes with.

The heater above described is in operation substantially similar to that described in my It passes into the side 2 (see Fig. 3) and rises up into a casing h, proje ction 61', divided by a diaphragm d which hereinbefore-inentioned patents; but the exter-connection to the said sections, also havpense and labor of molding the sections of ing' diaphragms b 0 and (1 the whole subthis heater are considerably diminished. stantially as described.
